preparation example Construction

[0024] In another aspect, a method for preparing DDGS feed is provided, the method comprising:

[0025] (1) Carrying out solid-liquid separation on the fermented waste mash to obtain filtrate and filter residue;

[0026] (2) Concentrating the filtrate to obtain a concentrated filtrate, and mixing the concentrated filtrate with the filter residue to obtain a mixed material;

[0027] (3) adding acetic acid and / or lactic acid to the mixed feed, and then drying to obtain the DDGS feed.

[0028] According to the present invention, the fermented waste mash has a meaning known in the art, and can be obtained by methods known in the art. The fermented waste mash refers to the product after alcohol is distilled from the fermented mash obtained after starch crops are fermented to produce alcohol.

[0029] Wherein, the starch crop may be, but not limited to, one of corn, potato (such as cassava) and wheat.

[0030] Preferably, the fermented waste mash contains 70-80% by weight of wate...

Embodiment 1

[0057] This embodiment is used to illustrate the DDGS feed provided by the present invention and its preparation method

[0058] (1) The waste fermentation mash is subjected to solid-liquid separation by centrifugation, the water content of the filter residue obtained from the solid-liquid separation is 50% by weight, and the filtrate is evaporated and concentrated at 65° C. to a water content of 65% by weight.

[0059] The concentrated filtrate and filter residue were mixed in such a ratio that the water content of the obtained mixed material was 62% by weight, and the pH value of the mixed material was adjusted to about 5.0 by using sodium hydroxide.

[0060] (2) Inoculate the seed liquid (Lactobacillus acidophilus) prepared above into 3 volume % in the mixed material that step (1) obtains, after mixing uniformly, under anaerobic condition (oxygen concentration is lower than 0.5mg / L ) at 35°C for solid-state fermentation until the pH of the fermentation product reaches 4.50....

Embodiment 2

[0063] This embodiment is used to illustrate the DDGS feed provided by the present invention and its preparation method

[0064] (1) The waste fermentation mash is subjected to solid-liquid separation by centrifugation, the water content of the filter residue obtained from the solid-liquid separation is 45% by weight, and the filtrate is evaporated and concentrated at 65° C. to a water content of 60% by weight.

[0065] The concentrated filtrate and filter residue were mixed in such a ratio that the water content of the obtained mixed material was 56% by weight, and the pH value of the mixed material was adjusted to about 4.5 by using sodium hydroxide.

[0066] (2) Inoculate the seed solution (Lactobacillus acidophilus) prepared above of 2 volume % into the mixed material that step (1) obtains, after mixing uniformly, under anaerobic condition (oxygen concentration is lower than 0.5mg / L ) at 38°C for solid-state fermentation until the pH of the fermented product reaches 4.20. ...

Abstract

The invention relates to the field of DDGS feed preparation, in particular to an application of acetic acid and / or lactic acid in improving the color and luster of DDGS feed, the DDGS feed and a preparation method of the DDGS feed. The method comprises the following steps: carrying out solid-liquid separation on the fermented waste mash to obtain a filtrate and filter residues; concentrating the filtrate to obtain the concentrated filtrate, and mixing the concentrated filtrate with the filter residues to obtain a mixed material; adding acetic acid and / or lactic acid into the mixed material, and then drying to obtain the DDGS feed. The method can effectively improve the color of the DDGS feed, improve the material grade and improve the feed value. When acetic acid and lactic acid are provided by preferably inoculating lactobacillus for fermentation, residual protein and polysaccharide in the waste mash can be further decomposed, so that amino acid and sugar are utilized by animals to the greatest extent, and the digestible, absorbable and utilization rate of the feed is increased. The method can also improve the smell of the materials, so that the materials have sour fragrance, stimulate the appetite of animals, increase the feed intake and improve the production performance.

Description

technical field [0001] The invention relates to the field of preparation of DDGS feed, in particular to the application of acetic acid and / or lactic acid in improving the color of DDGS feed, DDGS feed and a preparation method thereof. Background technique [0002] After the grain seeds or potatoes are fermented by yeast and distilled to remove ethanol, the remaining whole still (distiller's grains, containing at least three-quarters of solid content) is concentrated and dried to make a product, which is commonly referred to as DDGS feed . During the production and sales of DDGS feed, it is usually graded by color. For example, the first-grade product is defined as golden yellow without variegation; the second-grade product is defined as golden yellow with variegation; the third-grade product is defined as light brown; the fourth-grade product is defined as It is brown; the fifth-grade product is defined as dark brown. The difference in color will lead to a greater impact o...
